I got tagged in a PR about the release notes for ML-DSA Native 1.0.0 because I contributed a couple of minor API tweaks. I cannot overstate what an absolute joy the maintainers of this project were to work with.

They have to have ludicrously high quality requirements because pretty much every possible use of their codebase is security critical. And that doesn't seem to stop them from being amazingly welcoming and friendly to first-time contributors. I hope I do half as well as them in my own projects.
